The point is that your model of "freedom of speech" being usefully definable as a narrow legal constraint is about 50 years out of date with respect to the current censorship meta.
"Government can't throw you in jail for saying naughty stuff" is no longer useful - the tactics involved have moved past that.
Just how expansive a concept are your advocating? If you're only saying that aside from not throwing you in jail, government shouldn't coerce (or even incentivize) private parties to censor in ways the government would be prohibited from censoring, then I think you're right. But it's still not clear to me what concept of "free speech" you're actually advocating for.
Correct, that is an accurate characterization of my belief. Compare to your original comment:
> I think what you mean is that people are calling for internet platforms to kick out certain groups. This is in no way a call against freedom of speech.
The problem is that the causal factor causing e.g. twitter to evict people is not that "people are calling" for this action. The widespread coverage of certain people clamoring for censorship is only part of the legitimation process, not the actual reason twitter is performing the censorship. The actual reason twitter is performing the censorship is due to govt/elite pressure to do so.
So when you say "people are calling" for censorship, that's just what it looks like today when the US government censors people. They launder their actions through NGOs, civil rights lawsuits, selective prosecution, etc. so that people can diffuse any accusations of malfeasance with "well it's not the government doing it, so who cares"? It's untrue, and at some level it's irrelevant, but rhetorically it works.
